SPECIFICATION forming part of Letters Patent No. 370,840, dated October4, 1887.

Application filed October 4, 1886. Serial No. 215,Q04. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD WRIGHT, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented certain new and useful Improvements inSpinning-Mules, of which the following, together with the accompanyingdrawings, is a specification sufficiently full, clear, and exact to'enable persons skilled in the art to which this invention appertains tomake and use the same.

The object of my present invention is to provide an improvedspinningmachine for spinning wool and similar fibrous material, whichmachine will operate practically and successfully at a higher rate ofspeed than machines at present in use, and which can be run withcomparatively lighter power and attended with less labor and trouble;also, to render the machine more compact, so as to occupy less area offloor-space than the ordinary self-operating mules or jack-spinners,as-compared on the proportional amount of work performed.

One part of my invention relates to the construction and combination,in'a spinning-machine, of a set of spindles working at a stationaryposition, and a forwardly and backwardly moving carrier or roller-beam,upon which the roving-drums and roving-delivering rolls are supported,adapted to move toward and from the spindles, and means for effectingoperation thereof, as hereinafter set forth.

Another part of my invention relates to the construction and manner ofsupporting and retaining the roving-guides and deliveringrolls, by meansof a peculiar bearing-plate and holding devices, adapted for permittinga yielding and rocking action while confining the rolls inproper workingrelation.

A third part of my invention relates to the improved construction ofscroll mechanism for operating the roller-beam in its movements towardand from the spindles,andfor giving the peculiar variations andgraduations of movement required for difl'erent kinds and qualities ofstock, as more fully hereinafter set forth.

A fourth feature of my invention relates to the combination, with thescroll mechanism in aspinning-machine, of a yieldingtake-up or springdevices for compensating for the variations in the winding and unwindingof the scrolls in relation to each other, to prevent looseness of theropes or backlash in the mechanism.

A fifth feature of my invention relates to the construction and mannerof arranging the cam-shaft and its operating mechanism in combinationtherewith, as hereinafter explained.

A sixth part of my invention relates to the mechanism, in combinationwith the rollerbeam, for actuating the cam-shaft escapement and forcontrolling and adjusting the delivery of the roving.

The seventh part of my invention relates to the arrangement of thequadrant and windingcbain mechanism in a manner to attain a tripleaction or increased movement of the chain and winding-drum, ashereinafter explained.

The eighth part of my invention relates to the-combination, with thewinding-drum, of a disk and brake device controlled or operated by thecam-shaft, for preventing engagement of the winding-drum pawl with itsratchet during the time that the backi'ng'ofi mechanism is in action.

A ninth part of my invention relates to the construction and manner ofarranging the mechanism for transmitting power from the operating-shaftto the cylinder for the backing-off action, as hereinafter explained.

The tenth part of myinvention relates to an improved construction of thetwist-wheel and easing-in mechanism, wherein a lever press- 8 ingagainst the roller-beam actuated by a chain or band that winds onto thetwist-wheel shaft is employed.

The eleventh part of. my invention relates to the combination,with thecop-builder arm, 90 of animproved mechanism for controlling said arm inthe formation of the base of the cop, the distinctive feature of whichmechanism is the employment, in combination with a vertically-movingslide mounted on a reciprocat- 9 5 ing carrier and a short cop-formingloloclgthc upper surface of which is shaped to give rise and fall to thearm hinged to the top of said slide, of gage plates or movable inclinesadapted for raising both the slide and its hinged 10o cop-forming blockunder control of the 'copbuilder screw, as more fully hereinafterexplained. I

The twelfth part of my invention relates to an improved faller-tripmechanism operated in combination with the movable roller-beam andfaller lock bar for unlocking the fallers, and in connection with theescape-lever for letting off the escapement at the time for starting theindrawing scroll.

Other minor features of my invention will be understood from thedrawings and following description, the particular subject-matterclaimed being hereinafter definitely specified.

Fig. 27 is a longitudinal section at line .2 .2, Fig. 25.Fig. 28 is a longitudinal section of the take-up spring and its drum onthe back shaft, and Fig. 29 is a transverse section of the same.

Referring to parts, A denotes the main supporting-frame, composed ofsuitable upright castings, to which are secured the bearings for theback shaft, 13, and cylinder C,which latter extend longitudinallythroughout the length of the machine. The forward part of the frame,comprising the longitudinal step-girt A and bolster-rail A", isstationaryin position, andis boarded over, as indicated,to protect thelower part of the spindles S, the operating-bands Z), and the cylinder 0from accumulation of lint and waste.

At the top of the end and intermediate upright frames, A, I provideguideways a, preferably inclined downward toward the front of themachine, upon which guides there is supported a forwardly and backwardlymoving roller beam or carrier, D,whereon the rovingdrums D are mounted,so as to be moved toward and from the spindles to give the stretch forspinning the yarn.

The rovingdrums D are arranged for sup porting the roving-spools in thecustomary manner, being mounted on standards d, extending backward andupward from the rear part of the roller-beam D,whi1e along the frontpart of said roller'beam are arranged the roving-delivering rolls E E,the devices for supporting the top rolls in which are constructed in thepeculiar manner hereinafter described. The roller-beam is moved back andforth along the guides by means of bands or chains D", which are fixedto the under side of the beam, and which pass around sheaves orsprocketwheels B, keyed on the shaft B, and guidingsheaves S supportedby suitable brackets, at a position a short distance at the rear of thespindles, so that revolution of the shaft B effects the movement of theroller-bean1 and parts connected therewith toward and from the spindles.The chains D are arranged at intervals along the machine and serve tokeep the roller-beam square, or parallel with the line of the spindles,as said roller-beam is moved back and forth.

The driving-pulleys are arranged directly upon the cylinder-shaft 0,(see Figs. 1, 2, and 24,) and consist of four pulleys, G G G G", theouter pulley, G, being keyed to the shaft, the second pulley, G, looseupon the shaft, and provided with a long tubular hub, to which hub theinner pulley, G is keyed, while the third pulley, G", is arranged to runloose upon said tubular hub, this latter acting as a loose pulley forthe driving-belt when the machine is stopped. The inner pulley carriesthe belt F for driving the operating-shaft F of the spinner-head, whichshaft is provided with a pulley, F, as indicated in Fig. 2.Guide-pulleys F and F* are provided to give the requisite length, and tofacilitate taking up slackness of the belt, which can be done by adjusting one of said pulleys back and forth on the frame, itssupporting-stud being fitted to a slot, F, in the frame.

The operating-shaft F, cam -shaft I, and scrolls J and K are located atthe lower back part of the machine, in the relative positions indicatedin Figs. 1, 2, and 6, and supported in suitable bearings upon the frame.

The beltshipper fork is attached to a bar, H, mounted in suitablehearings on the frame, and arranged to have longitudinal rcciprocativeaction to carry the driving-belt to different positions on the face ofthe three pulleys G G G Said rod is moved in one direction by a spring,H, and in the other direction by a lever, H, actuated by the cam I onthe camshaft I. Said shipper-rod is also connected, by a suitableangle-lever, H, and chain H with the shipper-rod h, along the front ofthe machine, so that the attendant can at any time throw thedriving-belt onto the loose pulley G, by turning said rod when hedesires to stop the machine.

The draft-scroll J is supported to run loose on its shaft J, and isconnected thereto for operation by a clutch, J thrown into and out ofaction by means of a lever, J actuated by a cam, 1 on the cam shaft, anda suitable spring, .1, connected with the lever. Motion is transmittedto the shaft J by a train of gears, J J from the operating-shaft F. (SeeFig. 6.) The band or rope J of the draft-scroll J extends to and isattached to a winding-wheel or auxiliary scroll, M, fixed on the backshaft,

' B, which shaft is operated in one direction for moving the roller-beamfrom the spindles toward the rear of the machine by rotation of saiddraftscroll. The draft-scroll J is made with an overhanging peripheralrim, through which holes J are formed at short intervals, and the end ofthe rope is provided with a hook or a screw-clip, J whereby it can beconveniently attached and detached foradj usting it to differentpositions about the periphery of the scroll, and thus varying the draftas may be desired. To vary the draft to accommodate the requirements ofdifferent grades of stock, the attaching device at the end of the ropeis changed to different position on the periphery of the scroll, thusgiving a slightly-difierent speed and movement to the roller-beam D bycausing the rope to wind onto the lesser or. greater circles of thescroll.

The windingwheel M or auxiliary scroll is constructed with protuberantextensions m and m at the ends, whereby the surface on which the ropewinds is extended to a greater distance from the axis, thus increasingthe radius or leverage, so that the rope draws through a longer are, andthereby causes, in case of the extension m, a retarded action on themovement of the rollerbeam at the latter part of the stretch. Theforward extension, m, is made separable from the other part of thewheel, and is connected therewith by means of the attaching-bolts mpassing through slots m", in such a manner that y it can be adjusted todifferent positions about the peripheral circle, or detached from thewheel and interchanged for protuberant exten-' sions of different size,extension, shape, or curvature. The purpose of the forward extension, m,is to start the roller-beam away from the spindles by a slow and easyaccelererated motion, so as not to strain the partiallyspun yarn, and toavoid breaking down the ends.

Modifications of the extension-piece are shown in Figs. 1-1 and .11",adapted for imparting different qualities of movement to the back-shaftroving-beam.

The indrawing-scroll K is loose upon its shaft K,and is provided with aclutch, K for throwing it into and out of action, operated by a lever,K, under control of the earn 1 on the shaft I, and with a spring, K, forthrowing in the clutch when the lever is released. The rope or band Kfrom the indrawingscroll extends to and is attached to the periphery ofthe windingwheel N, fixed on the back shaft, B, which shaft is operatedby the rotation of said indrawing-scroll in a direction opposite to thatin which it is moved by the draft-scroll, thus effecting movement of theroller-beam D and spools of roving from the back of the machine towardthe spindles.

Connected with the scrolls Iemploy a spring take-up to compensate forthe difference in movement between the winding and unwinding of therespective scrolls, so as to keep the ropes taut at all times and toavoid backlash in the mechanism. Said'spring take-up is preferablyconstructed and arranged in the following manner: A drum or barrel, 0,(see Figs. 28, 29,) is mounted on the shaft B, which drum is composed oftwo parts-'viz., a hub and disk, 0, which is fixed or keyed to the shaftB, and a rim and supporting'disk, O, mounted loosely on said shaft B.Between these parts is confined a flat, volute, or coil spring, 0 oneend of which is attached to the hub, the part 0, while the other end ofsaid spring is attached to the rim or part O A strap, band, or chain,O*,exte11ds from the drum 0 to the hub of the scroll, or a wheel, 0,fixed thereon, the ends of the strap being respectively secured to andwound onto said drum in such manner that the strain of the spring willtend to rotate the scroll in a di-' rection opposite to the pull of thescroll-rope, thus keeping the rope pulled taut at all times. A similartake-up mechanism, 0 is employed for each of the scrolls J and K, andalso for rewinding the quadrant-chain. The two latter take-up devicesare indicated on the drawings at O and 0. (See Fig. 7.)

The springdrums O and 0 being mounted on the back shaft, B, which isoperated by the scrolls J and K, it will be noticed that the springs areonly uncoiled to an extent equal to the variations between the actionsof the two scrolls J and K in winding and unwinding, since the rotationof the shaft B accommodates the balance of the movement, and

the straps wind and unwind with the movement of the scrolls; hence thesprings are not strained to any great extent.

The cam-shaft I is mounted to turn in suitable bearings near theoperating-shaft F, and is provided with an escapement-wheel, I, havingfive stops, which works in connection with the let-0E ratchet mechanism1 operatinggears F F, and escape-lever to partially rotate saidcam-shaft at intervals, as required. A series of cams, I I, 1 1 ,1 1",and P", are mounted upon said camshaft I for throwing into and out ofoperation the various parts of the mechanism at the proper times. Astar-wheel, I, is fixed on the shaft I, and a presser-bar, S, iscombined therewith to hold the shaft, cams, and escapement from movingout of place, except when worked by the escapement. The escapement-wheel, cams, and star-wheel are illustrated in detail in Figs. 16 to20, inclusive. Said escapementwheel I and its ratchet mechanism areconstructed as follows:

The escapement-wheel I is mounted loose on the shaft I. On one side saidwheel is provided with a groove having five shoulders or offsets, i, toengage with the stop-stud p on the escape-lever P, and on the oppositeside it has two lugs, i. A disk, I", is fixed tight upon the shaftadjacent to the eseapement-wheel, and upon said disk there is supporteda pawl,

i", having a centrally-located tooth, i, that en-,

gages with the teeth of a ratchet-wheel, F", fixed to the side of agear, F, that runs loose upon the shaft I and meshes with and receivesmotion from a pinion, F, fixed on the operating-shaft F. The head of thepawl i is pivoted to the disk at i and its tail i projects laterallythrough a slot in the disk and is confined between the lugs i on theescapementwheel. A spring, '6 is attached to the disk, and pressesagainst the back of the pawl to force the tooth i into the ratchet.\Vhen the escape lever P is moved, so as to release its stud p from theshoulder of the escapementwheel, the spring i presses forward the pawl1', cansing its tooth to engage with the ratchet which is constantlyrevoli ing with the operatinggear F, and motion is transmitted throughthe pawl and disk to change the position of the cam-shaft, which movesone-fifth of a revolution, or until another shoulder of theescapement-wheel strikes the stud p of the escape-lever. This stops themovement of the wheel I, and the lugs i, acting against the tail of thepawl, forces the tooth of the pawl from the ratchet, and thus allows theratchet to revolve without moving the cam-shaft I until the stud of theescape-lever is again thrown from a shoulder of the wheel I, whenanother one-fifth revolution of the cam-shaft is effected.

The shaft I and disk I are pressed forward in the direction of rotation,so as to prevent the parts from turning back and allowing the pawl tocatch the ratchet by means of the spring-actuated arm S, provided with aroll, 8*, that presses forward the points of the star-wheel I,substantially in the manner as heretofore employed.

I do not claim novelty in the employment of an intermittently-rotatingcam-shaft for controlling the stopping and starting of mechanisms in aspinning-machine; but, as herein employed, the escapement mechanism foreffecting the stopping and starting of the camshaft is of improvedconstruction, and is adapted for giving five stops or intervals in therevolution of the shaft.

Upon the end of the scroll-shaft J there is mounted a sprocket-wheel, L,and clutch L, from which the roving-delivering mechanism is operated.Said clutch L is thrown into and out of action by means of a lever, L,controlled by a cam, I, on the cam-shaft I. (See Fig. 6.) Thesprocket-wheel L is connected, by achain, Z,with asprocket-wheehdmounted on the end ofthe roller-beam. Said chain passes around guidepulleys, sheaves, or sprockets Z Z i supported on studs fixed to theframe A, and guide-pulleys Z and l, mounted on v studs fixed to theroller-beam D, the parts being disposed substantially as shown in Fig.2, or so that the sprocket d will be operated by the action of the chainZ at whatever position the roller beam may occupy along the stretch. Theguide-pulley l is made adjustable for taking up the slack of the chain Zby having its stud clamped in a slot, Z, in the frame A. The sprocket dis provided with a gear fixed to the side thereof, which gear mesheswith an intermediate gear, 61, that in turn meshes with the gear 6, thatrevolves the roving-delivering rolls E E. The gear 0 is fixed to the endof the lower roll, E, which roll or the shaft thereof extends the lengthof the machine,-

being coupled together in sections.

The sprocket-wheel L and the sprockets and gearing d (1, and e, at theend of the rollerbeam, for driving the delivering-rolls may be formed ofdifferent relative size and arrange ment from that herein shown, orchanged for attaining different speeds of said deliveringrolls, asdesired; also, if desired, the chain 1 may be made in two parts, insteadof one continuous length, the portion extending from the lower part tothe upper part of the machine being formed in a separate piece or bandfrom that portion which extends from the rear part of the machine to thefront. In this case a double sprocket would be used in place of thewheel Z, one part of said sprocket carrying the upright portion of thechain or band and the other part of said sprocket carrying thehorizontal portion of the chain or band. This arrangement is indicatedby dotted lines in Fig. 2.

In the operation of the rolls E, the movement of the roller-beam is inopposite direction to the movement of the chain 1 while the roving isbeing delivered-that is, when the roller-beam is moving away from thespindles. Therefore one-halfofthe movement and speed, or substantiallyso, required for the rolls E is IlO obtained from the movement of therovingcarrier orroller-beam. Consequently the delivery of roving ispartially under control of the draft-scroll, and its speed of deliveryis thereby proportioned to the speed of the backward movement of theroller-beam, and partially under control of the'chain Z, running at theuniform speed of the machine; hence a slight excess of roving isdelivered beyond the amount of movement of the carrier or rollerbeam, tocompensate for what is taken up by the twisting during the time therollsE are turning.

As a modification in the construction of the roll-driving mechanism, inlieu of extending the chain Zto the front of the machine, said chain maybe arranged to drive a bevel-gear, L", at the rear, and a splined shaft,L, be arranged across the ends of the machine and connected with saidbeveled gear for its rotation. A beveled gear, L is then used to meshwith the rollgear e, the hub of which'beveled gear is arranged totraverse along and be operated by the splined shaft as the roller-beammoves back and forth. Such a modification is illustrated in Fig. 2 ofthe drawings. A rotary movement of said shaft is transmitted to therolls through the beveled gears L and 0, thus giving an action to therolls equivalent to that obtained with the use of the chain in themanner above specified.

The workingportion of the under roll, E, or that part on which the toprolls rest, is 1ongitudinally fluted with grooves and ridges aboutone-sixteenth of an inch apart, while the top rolls, E, are made with aplain surface and are mounted in pairs in a manner ca-- pable of arocking and yielding action. This construction permits of thedelivery-rolls readily and surely carrying through any small hardsubstances that may be in the roving, which would otherwise naturallychoke the rolls and break down the strands of roving.

The bottom roll is preferably formed hollow, as indicated in Fig. 26,and may be made of ordinary steam-pipe tubing properly dressed off onthe surface, and journals of solid bar metal may, if desired, beemployed at the ends of the tubular sections, where the roll takes itsbearings upon the frame.

The top rolls are constructed and supported as shown in detail in Figs.25, 26, and 27. Said rolls are coupled in pairs by a short axial shaft,6, and each pair is held in position by a bearing-plate, E, in themanner indicated. The central part of said bearing-plate is looked underafulcrum-bar, E fixed to the top of the roller-beam D, and said plate isprovided with a transverse groove or lugs, whereby it is retained inproper relation thereto. The head or front end of the plate is providedwith a groove which embraces the axial shaft 6 of the rolls, while therear end of said plate rests on a spring, E*, which spring forces upwardthe 'rear end of the plate, causing the forward end to press the toproll down upon the bottom roll. At the sides of the plate are formedslots or spaces eiwhich serve as guides for directing the strands ofroving centrally to the bite of the rolls. The roving guides or slotsmay be open at the top or side for the convenientintroduction of thestrand of roving. The recess in the head of the plate for the roll-shaftis longitudinally rounded at its upper part to allow rocking action ofthe rolls without rocking the bearing-plate.

The cam-shaft escapement-wheel I, having five stops orescapement-intervals, as hereinbefore stated, engages with the stud p ofthe escape-lever P. Said lever,which is arranged in upright position, ispivoted at P near the floor, and extends up to the top of the frame,where it connects with a longitudinally-movable bar or slide, R,arranged parallel with the guideway a, and provided at its ends withlugs r r, (adjustable, as indicated in Figs. 3,

4, and 5,) that engage the roller-beam at the forward and backwardlimits of its action, so that the said bar and the escape-lever will bemoved as the roller-beam is brought in contact with'either the forwardor rearward lug, and the cam-shaft escapement thereby released forchanging the posit-ion of the cams and bringing into action differentparts .of the mechanism at the proper time.

At an intermediate position upon the slide bar R, I arrange a finger orsmall angle-lever, R, pivoted upon the side of said bar,with its lowerarm engaging with a slotted block, R secured to a supporting-bar, Rfixed to the frame. When the slide-bar R is at forward position, therear end of the finger R projects above the top of said slide, and inthe backward movement of the roller-beam said finger is depressed by thebeam passing over it,which action moves the slide Rand escapement-leverP, letting off one step in the cam-shaft action. The purpose of thisfinger and the action instigated thereby is to throw out the clutchmechanism L and stop the delivery of roving. A series of holes, r, areformed in the slide R, and the pivoting stud r" of the lever can be setin either of said holes to adjust the lever to accommodate a long orshort delivery of roving, the block B being correspondingly adjustedalong the bar R by loosening its setscrew r and sliding it thereon tothe position desired.

The quadrant mechanism is arranged at the rear part of the frame and isconstructed as shown in detail in Figs. 13, 14, and 15. The quadrant-armQ, which is provided with a screw, q, for moving the nutalong the arm inQ? is a short shaft, Q, on one end of which is a bevel-gear, that mesheswith the gear 9 on the quadrant-screw q, and upon its other end aclutch, (Rand sprocket-wheel Q, actuated by a chain-baud, Qlwhich runsfrom the sprocket-wheel B on the back shaft, B. The quadrant-clutch Q isthrown into action by means of the forkf on the end of a rockershaft, f,the opposite end of which is provided with an arm or crank connected bya rod, f*, with an angle-lever, f, that is actuated by the drop-weight fconnected with the faller mechanism. \Vhen the under faller is drawndown below its proper level by the strain on the yarn, the weight fpresses down the levcrf, and thereby effects the throwing in of theclutch Q causing the nut or chain connection piece Q to be run out alongthe quadrant-arm Q, by the screw g. If preferred, in lieu of the shaftf,rodf and angle-leverf the connections for throwing in the quadrantclutch Q may be arranged in any convenient manner.

Pivoted to the nut or slide on the quadrantarm is a swinging piece, Q,in which is a sheave, Q. The quadrantchain Q", which leads to the drum 0on the cylinder-shaft, has its end connected to the swinging piece Q,thence passes forward around the sheave D, mounted on aforwardly-extending arm, D fixed to the roller-beam D, thence back andaround the sheave Q, then to the drum O to which the other end of thechain is attached. By this peculiar arrangement of the chain I obtain atriple action or multiplied movement and avoid the necessity of usinggears for increasing the movementof the winding-drum O.

No novelty is claimed in the use of the quadrant, the features of mypresent improvement being the improved arrangement of the chain and itsconnections, in combination with a quadrant, movable roller-beam, andwindingdrum, whereby the triple action is obtained.

The drum 0 is furnished with a take-up for preventing slack in thechain, which takeup consists of the spring mechanism 0 on the backshaft, similar to that above described for the scroll J, and a cord orband, 0 connecting the drum 0 with said spring-drum O to draw the drumin a direction opposite to the pull of the chain. In the presentinstancethe take-up band is shown passing around the guide-pulley near thefloor; but such band might be arranged to lead direct from thewinding-drum to the springdrum, if preferred, the gnide-pulley beingomitted. The winding-drum O is mounted to run loose on thecylinder-shaft. At its end is a ratchetwheel, 0, keyed to the shaft, and,a pawl, 0 for engaging saidratchet, is pivoted to the end of the drumand provided with a spring, 0, of the form indicated, which embraces acylindrical hub on the ratchet-wheel and acts to throw the pawl in orout, according to the direction of relative movement between the drumand ratchet. (See Figs. 15 and 16.)

The drum 0, ratchet (3*, pawl 0 and spring 0 are similar in constructionand action to those heretofore employed. In combination with theseparts, I employ a disk, T, mounted loose upon the cylinder-shaftadjacent to the ratchet-wheel, and provided with pins or lugs t,thatembrace theprojecting loop of the spring. A brake-lever, T is arrangedto press upon the periphery of the disk, under control of the cam I"upon the cam-shaft I, for retarding the movement of said disk during thetime of the backing-off action; hence while the cylinder is making thisbacking action the brake and disk, acting upon the spring C and pawl C,serve to hold the pawl out of engagement with the ratchet, so that thebacking-off mechanism can revolve the cylinder 0 in a reverse directionwithout affecting the winding-drum,while it effects the immediatethrowing in of the pawl to engage the ratchet the instant that thebacking-0d mechanism ceases to act, and draft upon the quadrant chain,which is attached to the winding-drum, commences. The brakelever T maybe made in a single piece, or, if preferred, may be made in two parts, tand i and provided with a screw, i, so as to be adjustable, as shown inFig. 16.

The drum, paw1,and ratchet, at U, for bringing the faller mechanism intoposition,are constructed to operate in the ordinary manner.

For imparting motion from the operatingshaft to the cylinder, whenbacking off, I employ a friction-wheel, V, mounted in a swingingbracket, V, suspended from a stud, V, parallel with the cylinder. Theshaft of the friction-wheel is provided with a pulley, V which isconnected by a short belt, V, with a pulley, C on the cylinder-shaft.The rim of the friction-wheel V is beveled on either side, and isarranged to swing into contact and engagement with a friction-wheel, Vmounted on the operating-shaft F, and having a V- shaped groove aboutits periphery, into which the rim of the friction-wheel fits. An arm, V,is attached to the swinging bracket, which engages with a cam, I, on thecam-shaft I, for swinging the friction-wheel into engagement at theproper time. Said arm is provided with an adj usting-screw, V wherebythe parts can be adjusted for giving frictional pressure between thewheels V and V". When the wheels V and V are brought into contact,motion is transmittedfrom the operating-shaft F through the wheel V andbelt V and pulleys V and C for rotating the cylinder and spindles in abackward direction. The frictional surfaces of the wheels V and V may befaced with leather or other suitable material, so as to give a highdegree of friction.

For easing-in the roller-beam to compensate for the shortening of theyarn by twisting, I employ a lever, W, fulcrumed near the floor, withits top end extending up in rear of the roller-beam, in position to beengaged thereby when said roller-beam is run back. A chain, IV, isconnected with said lever V, which passes to and is connected to theaxle or shaft W of the twist-wheel W, so as to be wound up by saidtwist-wheel for drawing the lever forward during the time the yarn istwisted. The twist-wheel is mounted on a swinging ICO bracket, W pivotedto the lower part of the frame A by the stud W and is rotated by a worm,F on the end of the operating-shaft 'F, against which it is held bymeans of a lever,

W attached to the bearing-bracket, which lever is pressed up by a cam, 1on the camshaft I during the time the twist-wheel is in operation. wormby its own gravity, when the cam 1 releases the lever W and saidtwist-wheel is rotated back to starting position by the unwinding of thechain W, which is effected by the action ofthe counterbalance-weightWflattached to an arm of the lever W in a manner to swing it'backward inopposition to the draft of the chain. A spring could, if desired, be

- used for pressing back the lever; but' I prefer aweight, as hereinshown. The twist-wheel is provided with a pin, 10, for stopping itsreturn motion at the proper position, which pin is interchangable to anyone of a series of holes formed in the wheel for gaging the amount oftwist put into the yarn in the customary mannor, the easing-in beingproportioned to the amount of twist, as the chain is more or less woundup accordingly as the twist-wheel revolves a greater or less distancefrom the point of starting. A series of holes are formed in the lever V,to permit of the chain being attached thereto at a higher or lowerposition, so as to give the lever a longer or shorter swing inproportion to the amount of chain wound up by a given movement of thetwist-wheel, thus adapting the mechanism for ready adj ustment of theeasing-in movement, so that it will compensate for the shortening of thestretch by the twisting of the yarnin different qualities ofstock, someof which shortens more than others by twisting. The easing mechanism,consisting of a lever and chain winding onto the twist-wheel axle, maybe used for casing: in the carriage on spinning-machines of otherconstruction than that herein shown, and I desire to include such use aswithin the scope of my present claim.

On the forward end of the twist-wheel shaft I arrange a cam or finger,W, which revolves into contact with an inclined lug or surface, F on abracket or arm connected with the es capement-lever, and whereby saidlever is moved to throwit off the escapement-stop and permit the changeof position of the cam-shaft, when sufficient twist has been given theyarn.

In my cop-builder mechanism the copbuilder arm Xis constructed andconnected in the manner substantially as heretofore employed.

The fallerdock chain Y and the regulatingchain Y are attached to thebacking-off clutch on the cylinder, the former passing to thefaller-lock for drawing it down beneath the roll at the front end of thecop builder lever, and the latter connected to the rear end of saidlever. Beneath the rear end of the lever, and mounted on a suitablesupport or frame, A, is a reciprocating carrier, 12, provided with arack, 13, which meshes with a pinion, 14, on

The twist-wheel drops from the' the end ofa short shaft, having on itsopposite end a sprocket-wheel, 15, which is driven by a chain, 16, froma sprocket-wheel, 17, on the back shaft, 13. Supported in the carrierthere is a vertically-moving slide, 18, to the upper front corner ofwhich the cop-forming block 20 is hinged in a manner to permit of itsrear end being raised and depressed. Said cop-forming block is made somesix inches (more or less) in length, and its upper surface is inclinedupward at either end, as indicated, the inclination being such asrequired to raise and depress the roll X and rear end of the lever X forimparting to the'fallers Y the proper action for winding the yarn ontothe cop with the suitable taper. Supported on the carrier 12, side byside with each other, are two wedges or inclined gage-plates, 21 and 22,which gage-plates are attached to a shoe, 23, guided upon the carrier12, carrying a nut. 24-, that works on the copbuilder screw 25, the gageplates being thereby supported in upright position to be movedlongitudinally along the carrier. The vertically-moving slide 18 isprovided with a stud or pin, 26, that rests upon the inclined top of thegage-plate 22. The cop-forming block 20 is provided with a pin or lug,27, that rests on the inclined top of the gage-plate 21. The gage-plates21. and 22, or one of them, is slotted, so that it can be adjustedlongitudinally in relation to the other to vary the relative actionbetween the slide 18 and the copforming block 20. The top of thegage-plate 21 is cut away level, or substantially so, at one end of theincline, so that the lug of the copformingblock will, at thecommencement of the cop, rest at a given height, while the slidecarrying the forward end of the forming-block moves downward tocompensate for the winding in of the cop at the base of the bobbinbefore the full form is completed, after which the ends move down theinclines of the gage-plates uniformly, or substantially so, with eachother. The gage-plates 21 and 22 are moved longitudinally along thecarrier by means. of the cop builder screw 25. Said screw is operated bya lever, 28, which swings on the axis of the screw, and carries a pawl,29, that engages a ratchet-wheel, 92, fixed on the end of the screw, androtates the screw as the lever is raised and depressed by running ontoan inclined guide-bar, 30, with the reciprocating movement of thecarrier. The bar 30 is pivoted at its rear end, and its front end issupported by a stud, 31, set into the sideof the frame. A series ofholes are formed in the frame for the stud 31, into either of which thestud can be inserted for supporting the bar 30 at greater or lessinclination, so as to give more or less movement to the lever 28 and thecop-builder screw 25, as required.

as indicates a spring device for raising the forward end of the lever X,and pressing the roll X down upon the former-block 20. Said ICO lever Xis fulerumed, as at as, on the part rier whereon the cop-buildermechanism is mounted, and its forward end is provided with a roll,beneath which the faller-lock Y books when the chain Y is wound up bythe backing-off action. The chain Y passes beneath the roll as, thenthrough the fallerlock bar Y, and connects with the spring y, fixed onsaid bar in the ordinary manner. The upper end of the bar Y is pivotedto an arm or crank fixed on one of the taller-rods, and the fallers areconstructed and arranged to operate in the common well-known manner.

Z indicates a tripping-lever pivoted or fulcrumed to a suitableeye-block, 2, on the floor, and extending upward at the front of themachine, with its top end, .c,in position to engage with the roller-beamD, or an arm, D' attached thereto, whereby the lever will be swungforward when the roller beam approaches the spindles S. The lower partof the lever is made with two sides connected by cross-bars to givelightness and strength in construction. Said lever is provided with a.lateral arm, Z, that passes behind the fatherlock bar Y and serves tothrow the faller-lock out of engagement with the roll m of thecopbuilder lever X when the roller-beam D or its arm D acts against thelever Z: Atapered adjustable striking-piece, y, is fixed, by means ofbolts that pass through slots,as indicated in Fig. 23, on thefallerlock, against which the arm Z works, and by means of whichadjustment is attained for releasing the look at the proper instant oftime.

A rod, Z connects the tripping-lever Z with theescapementleverl.Theforwardendofsaid rod has a longitudinal slot, 2, and is attached tosaid trip-lever by a stud, .2 that runs in the slot, so that the lever Zcan swing forward without actuating the rod, but will press back saidrod when the fallenlock is drawn back against it by the chain Y at thelast extent of its backward movement,and thereby throws off theescapement and permitsa change of position of the cam-shalt for bringinginto action the indrawingscroll and stopping the backingoff action.

The operation of my improved spinning-machine is as follows: Commencingwith the roller-beam and rolling-drums at a position near the spindlesand just starting for spinning a stretch. Theealnshaftandescapementarethen at the position as indicated in Figs. 17 to 20.

.The driving-belt at this time is on the first pulley, G, and the secondpulley, G, thus operating the cylinder and spindles and also theoperating-shalt F, which operating-shaft runs during the entireoperation, except when the machine is stopped by shifting the belt ontothe loose pulley G The clutch J of the draftscroll J is .in mesh foraction, and also the clutch L, driving the mechanism whereby therovingisdelivercd. Now,astheroller-beamD moves backward, the roving ispaid out by the delivery-rolls until the beam D comes in contact withand depresses the lever or finger R, which action moves the bar R andescapementlever P, throwing the stud 1) of the lever from the shoulderof the escapement-wheel and permitting the first change in the positionof the cam-shaft. At this change the cam I on the cam-shaft throws outthe clutch L, and thus stops the delivery of the roving. "When thecarrier or roller-beam D reaches its backward limit of action, itengages the lug r at the rear end of the slide-bar R, and by moving saidbar and the lever P again trips the escapemcnt, allowing the cam-shaftto make its second change of position. At this time the cam I releasesthe clutch J thus throwing the draftscroll out of action. The cam 1"raises the twist-wheel into mesh with the worm on the operatingshaft,thus bringing the easing'in mechanism into action. The machinethen runson until sufficient twist has been imparted to the yarn,when the cam \Vstriking the incline bracket, moves back the escape-lever, releasing theescapement and permitting the third change in the position of thecam-shaft.

At this third change the cam 1 swings off 0 from the lever W and thetwist-wheel drops from the worm F and is turned back to place by theunwinding ofthe chain \V. At the same time the cam I operates theshipper h to shift the driving-belt from the pulleyG, so that 1t willrun on the pulley G while at the same time the cam I swings thefriction-wheel V into engagement with the wheel V for turning thecylinder backward or backing off the spindles also at the same time thecam 1 forces the friction-brake T against the per phery of the disk Tfor holding out the windingdrum clutch during the back-off action. It

will be understood that the driving-belt at all timesruus upon andoperates the pulley G, and that in shifting from pulley G to pulley Gthe belt is moved across said central pulley, G, so that its edge willlap onto either one or the other of the two pulleys G or G", while atthe same time embracing pulley G. The backward rotation of the cylinder,effected by the frictionwheels V V and their connections, winds up thefaller-lock chain Y, drawing the faller-lock Y beneath the roll 00'ofthe cop-builder arm X, and said faller-loek, as it comes intoposition, presses back the arm Z of the trip-lever Z, which movementalso acts, through the rod Z upon the escape-lever to release theescapement and eifeet the fourth change of position of the cam-shaft. Atthis fourth change the cam 1 releases the brake T". The cam 1, throughthe lever K throws in the clutch K of the indrawing-scroll K, by whichthe back shaft is operated to move forward the roller-beam; also at thesame time the cam 1 throws out the friction-wheel V, stopping thebacking-off action. As the rollerbeam moves forward, the chain Q isunwound from the winding-drum and the cylinder and spindles are revolvedby said winding-drum for winding the yarn upon the bobbins. The form ofwinding on is controlled by the cop-builder mechanism acting through thefaller-lock bar and fallers in a general way,

' change in the position of the cam-shaft, bringing said cam-shaft roundto its original position. At this change the cam I actuates the lever Land throws in the clutch L. The cam 1 actuates the lever J and throws inthe clutch J of the draft-scroll J. The cam 1 actuates the lever K ofthe clutch K of the indrawingscroll K. The cam l releases thebelt-shipper H, which is actuated by its spring H to shift the belt'fromthe pulleys G2 G over upon the pulleys G G, thus bringing the parts intocondition as first above stated, when the operation as above describedwill be repeated.

At any time, if the attendant desires to stop the machine, he rotatesthe shipper-rod h, which, by drawing on the chain H ,thereby moves theshipper, so that the belt is shifted entirely onto the loose pulley GWhat I claim as of my invention, and desire to secure by Letters Patent,is-
